Component Inspection

  1. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I
    1. Disconnect intake valve timing control solenoid valve harness connector.
    2. Check resistance between intake valve timing control solenoid valve terminals as per the following.
      RESISTANCE REFERENCE CHART

      Terminals Resistance
      1 and 2 7.0 - 7.5 Ω [at 20°C (68°F)]
      1 or 2 and ground ∞ Ω
      (Continuity should not exist)

      Is the inspection result normal? 

      YES >> GO TO 2.

      NO >> Replace malfunctioning intake valve timing control solenoid valve. Refer to "EXPLODED VIEW ".

  2. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
    1. Remove intake valve timing control solenoid valve.
    2. Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Check that the plunger moves as shown in the figure.
      CAUTION: Never apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in intake valve timing control solenoid valve.
      NOTE: Always replace O-ring when intake valve timing control solenoid valve is removed.
